                                    Features Of Fluke 434/435
Introduction
The Analyzer offers an extensive and powerful set of
measurements to check power
distribution systems. Some give a general impression of
power system performance.
Others are used to investigate specific details. This
chapter gives an overview on how to
perform measurements in a logical order.
The measuring modes are described in detail in Chapter 7 to
18. Each measuring mode is
explained in a separate chapter.
Fluke 435 has additional features such as Mains Signaling,
Logging, 0.1 % voltage
input accuracy acc. to IEC61000-4-30 2003 Class A, extra
memory to store Logging
Data, Power Log software, flexible current clamps, and a
heavy duty trolley style
case.
In Fluke 434 the functions Mains Signaling and Logging can
be installed optionally.
If not installed, they show up in the menu in grey color.
General Measurements
To check if voltage leads and current clamps are connected
correctly, use Scope
Waveform and Scope Phasor. The clamps are marked with an
arrow to facilitate proper
signal polarity. Chapter 6 Input Connections explains how to
make connections.
To get a general impression of the quality of a power system
use MONITOR. The
MONITOR key displays a screen with Bar Graphs that show
quality aspects of the phase
voltages. A Bar Graph changes from green to red if the
related aspect does not meet the
limits. Up to 7 different sets of limits can be chosen for
Fluke 435: a number of them are
user programmable. One of these sets are the limits
according to the EN50160 norm. For
each quality aspect submenus with detailed information are
attainable via the function
keys F1 ... F5.
Numerical data is shown by Volts/Amps/Hertz. For this press
the MENU key. Then
select Volts/Amps/Hertz and press F5 – OK to display a Meter
screen with the present
values of voltages (rms and peak), currents (rms and peak),
frequency and Crest Factors
per phase. Press F5 – TREND so display the course over time
of these values.
Measuringmodes to investigate details
Phase voltages. Should be close to the nominal value.
Voltage waveforms must be a sine
wave that is smooth and free from distortion. Use Scope
Waveform to check the
waveform shape. Use Dips & Swells to record sudden voltage
changes. Use Transients
mode to capture voltage anomalies.
Phase currents. Use Volts/Amps/Hertz and Dips & Swells to
check current/voltage
relations. Use Inrush Current to record sudden current
increases like motor inrush.
Crest Factor. A CF of 1.8 or higher means high waveform
distortion. Use Scope
Waveform to see waveform distortion. Use Harmonics mode to
identify harmonics and
THD (Total Harmonic Distortion).
Harmonics. Use Harmonics mode to check for voltage and
current harmonics and THD
per phase. Use Trend to record harmonics over time.
Flicker. Use Flicker to check short and long term voltage
flicker and related data per
phase. Use Trend to record these values over time.
Dips & Swells. Use Dips & Swells to record sudden voltage
changes as short as half a
cycle.
Frequency. Should be close to nominal value. Frequency is
normally very stable. Select
Volts/Amps/Hertz to display frequency. The course of
frequency over time is recorded in
the Trend screen.
Unbalance. Each phase voltage should not differ more than 1
% from the average of the
three. Current unbalance should not exceed 10 %. Use Scope
Phasor or Unbalance mode
to investigate unbalances.
Mains Signaling. Can be used to analyze the level of remote
control signals that often are
present on power distribution systems.
Logger. Allows you to store multiple readings with high
resolution in a long memory.
